1. command when you start nodes.
2. wsrep_cluster_address(my.cnf setting) of all nodes
3. wsrep_incoming_addresses (whether all the possible node is added) which you can get by following command.
mysql> show status like "wsrep%";

I see how you looked at the source code to find the error text about blacklisting, so that's cool. I guess would have to know that blacklisting is bad (I guess I will need to read about it). I saw so many blacklisting messages, and it syncing fine, that I thought it was ok.

Question: how does one match/search an issue to the bug list? Meaning, how did you even know to look at this particular bug on the bug list?

This configuration was automatically done by SeveralNine's ClusterControl. These three nodes are geographically dispersed (different cities), different MySQL segments, connected by VPN. It works great most of the time, and they are synced, unless the mysqld crashes. It only seems to crash on the two slow machines (Node2 and Node3).

free word search by "blacklist" because this is the key and galera specific problem.
